I have the same question. 65 dart convertible and wondering where to put the speakers.
Kick panels seem like an obvious choice but I can't find any off the shelf for a 65. Looks like I'll have to get creative with some fiberglass.
Did you mount the tweeters in the center, where the stock am speaker normally goes?
I think a subwoofer could go under the seats but I'm afraid the back seat passengers will hear nothing but bass.
I agree that cutting into the fiberglass convertible side panels is not a good option.
